What Credit Score Do You Need for a Mortgage?
Your credit score is one of the most powerful numbers in the home-buying process. It determines whether you qualify for a mortgage at all, which loan programs are available to you, and — most importantly — what interest rate you'll pay. On a 30-year mortgage, even a 0.5% rate difference can cost or save $30,000-$50,000 in total interest. Understanding where you stand and how to improve it before applying can be worth thousands of dollars.
Minimum Credit Scores by Loan Type
| Loan Type | Minimum Score | Ideal Score | Key Details |
|---|---|---|---|
| Conventional Loan | 620 | 740+ | Best rates, no upfront MIP |
| FHA Loan | 580 (3.5% down) | 680+ | 500-579 requires 10% down |
| VA Loan | No official min (lenders: 580-620) | 680+ | Best overall terms for veterans |
| USDA Loan | 640 | 680+ | Rural/suburban areas, 0% down |
| Jumbo Loan | 700-720 | 760+ | Loans above conforming limits |
How Your Score Affects Your Rate
The interest rate difference between a 620 and 760 credit score is significant — typically 1.5-2% on a conventional mortgage. Here's what that means in real dollars on a $300,000 loan:
| Credit Score | Approximate Rate | Monthly Payment | Total Interest (30yr) |
|---|---|---|---|
| 760+ | 6.5% | $1,896 | $382,600 |
| 720-759 | 6.75% | $1,946 | $400,400 |
| 680-719 | 7.0% | $1,996 | $418,500 |
| 640-679 | 7.5% | $2,098 | $455,300 |
| 620-639 | 8.0% | $2,201 | $492,600 |
The difference between a 620 and 760 score on a $300,000 mortgage: $305/month more, $110,000 more in total interest paid. This is why working on your credit before applying is so valuable.
What's in Your Credit Score
- Payment History (35%): Most important factor. Every late payment hurts.
- Credit Utilization (30%): How much of your available credit you're using. Under 30% is good, under 10% is excellent.
- Length of Credit History (15%): Older accounts help. Don't close old cards.
- Credit Mix (10%): Having different types of credit (cards, installment loans) helps slightly.
- New Credit (10%): Recent applications temporarily lower your score.
How to Improve Your Score Before Applying
Pay Down Credit Card Balances (Biggest Impact)
Credit utilization is recalculated every month when your statement closes. Paying down a maxed-out card from 90% to 10% utilization can add 50-100 points to your score within 30-60 days. This is the fastest way to boost your score.
Dispute Credit Report Errors
Get your free credit reports from AnnualCreditReport.com and review for errors. Incorrect late payments, accounts you don't recognize, or wrong balances can all be disputed. Errors affect about 20% of credit reports — they're more common than most people realize.
Don't Close Old Accounts
Closing a credit card reduces your available credit (hurting utilization) and may shorten your average credit history. Keep old accounts open, even if you rarely use them.
Become an Authorized User
If a family member has a credit card with a long positive history, ask to be added as an authorized user. Their account history can appear on your report and boost your score.
Avoid New Credit Applications
Each hard inquiry from a new credit application temporarily lowers your score by 5-10 points. Don't open new accounts in the 6-12 months before applying for a mortgage.
Mortgage Rate Shopping and Your Score
When you apply for multiple mortgages within a short window (14-45 days depending on scoring model), all those inquiries count as a single inquiry. Shop aggressively — comparing 3-5 lenders won't hurt your score if done within this window.
How Long Does Credit Improvement Take?
- 30-60 days: Paying down balances shows up quickly
- 3-6 months: Establishing payment patterns, removing small errors
- 12-24 months: Significant rebuilding from poor credit
- 7 years: Negative marks (late payments, collections) fall off automatically
